الماۤئدة — Al-Ma'idah Ayat 51
۞ يٰٓاَيُّهَا الَّذِيْنَ اٰمَنُوْا لَا تَتَّخِذُوا الْيَهُوْدَ وَالنَّصٰرٰٓى اَوْلِيَاۤءَ ۘ بَعْضُهُمْ اَوْلِيَاۤءُ بَعْضٍۗ وَمَنْ يَّتَوَلَّهُمْ مِّنْكُمْ فَاِنَّهٗ مِنْهُمْ ۗ اِنَّ اللّٰهَ لَا يَهْدِى الْقَوْمَ الظّٰلِمِيْنَ
Yā ayyuhal-lażīna āmanū lā tattakhiżul-yahūda wan-naṣārā auliyā'(a), ba‘ḍuhum auliyā'u ba‘ḍ(in), wa may yatawallahum minkum fa innahū minhum, innallāha lā yahdil-qaumaẓ-ẓālimīn(a).
"O you who have believed, do not take the Jews and the Christians as allies. They are [in fact] allies of one another. And whoever is an ally to them among you - then indeed, he is [one] of them. Indeed, Allah guides not the wrongdoing people."
